Kia Niro Luggage Compartment Bulb Size

Additional Notes

• The Kia Niro uses two distinct festoon bulb types across its model years for the luggage compartment: the DE3425 for 2021-2024 and the 6461 for 2017-2019.
• Both the DE3425 and 6461 are festoon-style bulbs, meaning they mount horizontally between two end contacts within a fixed-length housing rather than using a screw or bayonet base.
• The DE3425 is an ANSI-standardized bulb rated at 12V and measures 41mm in length, with end-cap contacts at each terminal.
• The 6461 is also an ANSI-standardized 12V bulb, rated at 5W, with a 36mm length and an SV8.5 base designation.
• The SV8.5 base on the 6461 refers to a festoon base with an 8.5mm contact cap width, a detail that distinguishes it from other festoon types at the socket level.
• The DE3425 and 6461 are not interchangeable despite both being festoon bulbs, as they differ in length by 5mm and use different base specifications, which affects physical fitment in the luggage compartment housing.
• The 2021-2024 Kia Niro models share a single bulb specification for the luggage compartment, indicating a consistent socket design across those four model years.
• Both bulb types conform to ANSI standards applicable in the United States and Canada, meaning they follow a defined set of dimensional and electrical tolerances recognized across those markets.
